COMBINATION GAS AND ELECTRIC LAMP.

Specification of Letters Patent.

Patented J an. 19, 1915.

Application filed September 5, 1914. Serial No. 860,330.

To all whom it may concern Be it known that I, ALFRED H. H'UMPHREY, a citizen of the United States, residing in the city and county of New York, State of New York, have invented certain new and useful Improvements in Combination Gas and Electric Lamps, of which the following is a specification.

This invention relates to improvements in combination gas and electric lamps.

My invention relates particularly to improvements in combination gas and electric lamps of indirect type or semi-direct type as they are sometimes called, thatis, lamps in which the light is reflected upwardly from an opaque or a translucent globe closing the lower part of the lamp.

The main objects of this invention are: First, to provide an improved combination gas and electric lamp of the indirect type. Second, to provide an improved combination gas and electric lamp of the indirect type in which the globe is closed beneath and open at the top and the parts so arranged that the light rays radiating and refiected upwardly are practically shadowless. Third, to provide an improved combination gas and electric lamp of the indirect type in which the parts are so arranged that the products of combustion escape without unduly heating the electric lamps and their connections and at the same time do not interfere with the air supply to the gas burner at the mixing tube parts or at the I point of combustion. Fourth, to provide an improved combination gas and electric lamp in which the burner and the electric lamps are so disposed that the light is uniformly distributed and without spot light effects.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A. structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

Figure I is a side view of a structure embodying the features of my invention. Fig. II is a plan view of the bottom portion of the lamp, the side members of the frame being shown in the horizontal section. Fig.

III is an enlarged detail plan view showing the mounting of one of the electric lamps. Fig. IV is a detail inside elevation showing further details of the mounting of one of the electric lamps. Fig. V is a detail horizontal section on a line corresponding to line 5-5 of Fig. IV. Fig. VI is a detail vertical section on a line corresponding to broken line 66 of Fig. III. Fig. VII is a detail horizontal section on a line corresponding to line 7-7 of Fig. 1, showing details of the top of the lamp. Fig. VIII is a detail vertical section on a line corresponding to line 88 of Fig. VII. Fig. IX is a detail vertical section on a line corresponding to line 9-9 of Fig. VII.

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction .of the little arrows at the ends of the section lines.

Referring to the drawing the supply pipe 1 is adapted asa support for the lamp. I provide a skeleton frame consisting in the structure illustrated of the coupling or top member 2 having radial arms 3. Depending from these arms 5 are rod like side members 4:, 5, 6, and 7. These side members diverge downwardly to the band-like annular supporting member 8 mounted on their lower ends. At the other ends of the side members t is an ornamental member 9 which embraces the top member 2. The side members 4 are preferably provided. with ornamental portions 10 at their upper ends and ornamental portions 11 at their lower ends which terminate in cross portions 12 disposed on the inside of and secured to the supporting member 8 by means of screws 13. The supply pipe 1 is provided with an ornamental ceiling member 14. The side member 4 is adapted as a gas delivery conduit. The side member 5 is adapted as a conduit for the circuit wires. The side member 6 is adapted as a gas conduit for the pilot burner. The side member 7 in the structure illustrated is a dummy.

The burner 15 is provided with a horizontally disposed mixing tube 16 arranged in the plane of the supporting member 8, the width of the supporting member being approximately the diameter of the mixing tube. The burner is supported by the mixing tube and the inwardly projecting rod 17 which is passed through an car 18 on the burner, the burner being secured on the rod by the nuts 19. The burner is thus centrally supported without encumbering the space within the lamp. The pilot burner 20 projects inwardly from the conduit 6 into suitable proximity to the burner.

The main burner is controlled by a valve designated generally by the numeral 22 while the pilot is regulated by the valve 23. As the details of these valves form no part of my. present invention, they are not illustrated or described in detail herein.

The globe holder member 24- is hinged at 25 to the supporting member 8 so as to embrace the same as shown, the globe holder being held in its closed position by the spring pins 26. Between the supporting member 8 and the globe holder, I arrange brackets for the circuit wires 27. These brackets in the structure illustrated consist of the blocks 28 of insulating material and the clip members 29, the blocks being secured to the clip members by the bolts 30. The clip members are provided with flanges 31 which embrace the supporting band 8 as clearly shown in Fig. VI, the wire brackets are secured upon the supporting members by means of the lamp supporting brackets 32which are arranged on the inner side of the supporting member 8 and slidably engage the flanges of the wire supporting brackets. These brackets 32 are f-shaped, the inwardly projecting arms 33 having threaded nipples 34 upon which the lamp sockets 35 are mounted. The lamps 36 are supported on these brackets in a chord-like relation to the supporting member and in substantially the plane of the supporting member although they are preferably slightly inclined as indicated in Fig. IV. The circuit wires are passed down through the conduit 5 and are supported by the wire supporting brackets between the globe holder and supporting members as clearly shown in Fig. II, suitable terminals 37 lead from the wires 36 to the lamps. The circuit wires are retained upon the insulating blocks by means of the caps 38 also of insulating material. By this simple means, the lamp and circuit wire brackets are properly supported. The lamps may be positioned as desired, that is, the same general structure is adapted for two, three or four electric lamps as may be desired.

The electric lamps in the position in Fig. II are out of the way of the products of combustion, which pass upwardly around in the burner and at the same time they are positioned so that the light therefrom blends with the light from the gas burner producing a highly satisfactory result.

The globe 39 is open at the top and is mounted upon the globe holder to embrace the burner and lamps from below. The globe is preferably semi-opaque or translucent.

The structure being entirely open above the burner, there are no operating or metal parts to obstruct light rays radiating from the burners and lamps and reflected from the inside of the globe upwardly through the skeleton frame. Further, all the operating parts of the lamp and metal connections, the ornamental side members, the ornamental globe ring, together with the valves are entirely outside of the path of the products of combustion and do not become heated enough to interfere with the successful operation of the lamp or ,to spoil the finish. Further, owing to the unobstructed center above the burner and the wide open globe of reflected light rays are distributed from the inner surface of the globe over a wide area and the reflected heat rays are to a large degree distributed as are the light rays. The lamp being entirely open above causes a central upward current and draws fresh air to the burner to properly maintain combustion at that point and also to furnish a supply of fresh air to the port 40 on the mixing tube. The light is reflected and radiated from the lamp upwardly so that there are no shadows which is a highly desirable feature. My improved lamp is also very desirable on account of the ease with which it may be cared for as the burner parts and lamps are all fully accessible when the globe is open both from above and from below.

I have illustrated and described my improved lamp in detail in the form in which I have embodied the same. I have not attempted to illustrate or describe the various modifications which I contemplate as practical and in some cases desirable as the disclosure made will enable those skilled in the art to which my invention relates to embody or adapt the same as may be desired. 1 desire, however, to be understood claiming my improvements specifically in the form illustrated as well as broadly within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
